Answer:
the slope is 2
Step-by-step explanation:
take y2 and y1 and subtract them, 11 - 5 = 6
then take x2 and x1 and subtract them, 5 - 2 = 3
then divide those 2 numbers, 6/3 and you get 2
Answer:
The correct set of hypotheses is
: d=80 degrees
: d>80 degrees
Step-by-step explanation:
The weatherman claims that the average temperature during July in Chattanooga is 80 degrees or less. To test this claim, following hypotheses need to be taken:
Let d be the the average temperature during July in Chattanooga, then
: d=80 degrees
: d>80 degrees
Answer:
(0, 24]
Step-by-step explanation:
The horizontal extent of the graph is from 0 to 24. There is an open circle at x=0, and a closed circle at x=24. Hence, the domain of the function is ...
0 < x ≤ 24
In interval notation, this is
(0, 24]

We note that this is not one of your answer choices. You may want to discuss this with your teacher.
Let's define the vectors:
U = (4.4)
V = (3.1)
The projection of U into V is proportional to V
The way to calculate it is the following:
Proy v U = [(U.V) / | V | ^ 2] V
Where U.V is the point product of the vectors, | V | ^ 2 is the magnitude of the vector V squared and all that operation by V which is the vector.
We have then:
U.V Product:
U.V = (4,4) * (3,1)
U.V = 4 * 3 + 4 * 1
U.V = 12 + 4
U.V = 16
Magnitude of vector V:
lVl = root ((3) ^ 2 + (1) ^ 2)
lVl = root (9 + 1)
lVl = root (10)
Substituting in the formula we have:
Proy v U = [(16) / (root (10)) ^ 2] (3, 1)
Proy v U = [16/10] (3, 1)
Proy v U = [1.6] (3, 1)
Proy v U = [1.6] (3, 1)
Proy v U = (4.8, 1.6)
Answer:
the projection of (4,4) onto (3,1) is:
Proy v U = (4.8, 1.6)
Is that 5 hours 2 mins or 2.5min
